Currently the controller handles single stream only. So, Ignore Packet
Pending bit for stream selection and don't search for another stream if
the host sends Data Packet with PP=0 (for OUT direction) or ACK with
NumP=0 and PP=0 (for IN direction). This slightly improves the stream
performance.

critclk_systems DMI table
pmc_plt_clk* clocks are used for ethernet controllers, so need to stay
turned on. This adds the affected board family to critclk_systems DMI
table, so the clocks are marked as CLK_CRITICAL and not turned off.
This replaces the previously listed boards with a match for the whole
device family CBxx63. CBxx63 matches only baytrail devices.
There are new affected boards that would otherwise need to be listed.
There are unaffected boards in the family, but having the clocks
turned on is not an issue.

Current trusted keys framework is tightly coupled to use TPM device as
an underlying implementation which makes it difficult for implementations
like Trusted Execution Environment (TEE) etc. to provide trusted keys
support in case platform doesn't posses a TPM device.
Add a generic trusted keys framework where underlying implementations
can be easily plugged in. Create struct trusted_key_ops to achieve this,
which contains necessary functions of a backend.
Also, define a module parameter in order to select a particular trust
source in case a platform support multiple trust sources. In case its
not specified then implementation itetrates through trust sources list
starting with TPM and assign the first trust source as a backend which
has initiazed successfully during iteration.
Note that current implementation only supports a single trust source at
runtime which is either selectable at compile time or during boot via
aforementioned module parameter.

The current implementation appends a migratable flag to the end of a
key, meaning the format isn't exactly interoperable because the using
party needs to know to strip this extra byte. However, all other
consumers of TPM sealed blobs expect the unseal to return exactly the
key. Since TPM2 keys have a key property flag that corresponds to
migratable, use that flag instead and make the actual key the only
sealed quantity. This is secure because the key properties are bound
to a hash in the private part, so if they're altered the key won't
load.
Backwards compatibility is implemented by detecting whether we're
loading a new format key or not and correctly setting migratable from
the last byte of old format keys.

Modify the TPM2 key format blob output to export and import in the
ASN.1 form for TPM2 sealed object keys. For compatibility with prior
trusted keys, the importer will also accept two TPM2B quantities
representing the public and private parts of the key. However, the
export via keyctl pipe will only output the ASN.1 format.
The benefit of the ASN.1 format is that it's a standard and thus the
exported key can be used by userspace tools (openssl_tpm2_engine,
openconnect and tpm2-tss-engine). The format includes policy
specifications, thus it gets us out of having to construct policy
handles in userspace and the format includes the parent meaning you
don't have to keep passing it in each time.
This patch only implements basic handling for the ASN.1 format, so
keys with passwords but no policy.

In TPM 1.2 an authorization was a 20 byte number. The spec actually
recommended you to hash variable length passwords and use the sha1
hash as the authorization. Because the spec doesn't require this
hashing, the current authorization for trusted keys is a 40 digit hex
number. For TPM 2.0 the spec allows the passing in of variable length
passwords and passphrases directly, so we should allow that in trusted
keys for ease of use. Update the 'blobauth' parameter to take this
into account, so we can now use plain text passwords for the keys.
so before
keyctl add trusted kmk "new 32 blobauth=f572d396fae9206628714fb2ce00f72e94f2258fkeyhandle=81000001" @u
after we will accept both the old hex sha1 form as well as a new
directly supplied password:
keyctl add trusted kmk "new 32 blobauth=hello keyhandle=81000001" @u
Since a sha1 hex code must be exactly 40 bytes long and a direct
password must be 20 or less, we use the length as the discriminator
for which form is input.
Note this is both and enhancement and a potential bug fix. The TPM
2.0 spec requires us to strip leading zeros, meaning empyty
authorization is a zero length HMAC whereas we're currently passing in
20 bytes of zeros. A lot of TPMs simply accept this as OK, but the
Microsoft TPM emulator rejects it with TPM_RC_BAD_AUTH, so this patch
makes the Microsoft TPM emulator work with trusted keys.

The TCG has defined an OID prefix "2.23.133.10.1" for the various TPM
key uses. We've defined three of the available numbers:
2.23.133.10.1.3 TPM Loadable key. This is an asymmetric key (Usually
RSA2048 or Elliptic Curve) which can be imported by a
TPM2_Load() operation.
2.23.133.10.1.4 TPM Importable Key. This is an asymmetric key (Usually
RSA2048 or Elliptic Curve) which can be imported by a
TPM2_Import() operation.
Both loadable and importable keys are specific to a given TPM, the
difference is that a loadable key is wrapped with the symmetric
secret, so must have been created by the TPM itself. An importable
key is wrapped with a DH shared secret, and may be created without
access to the TPM provided you know the public part of the parent key.
2.23.133.10.1.5 TPM Sealed Data. This is a set of data (up to 128
bytes) which is sealed by the TPM. It usually
represents a symmetric key and must be unsealed before
use.
The ASN.1 binary key form starts of with this OID as the first element
of a sequence, giving the binary form a unique recognizable identity
marker regardless of encoding.

We have a need in the TPM2 trusted keys to return the ASN.1 form of the TPM
key blob so it can be operated on by tools outside of the kernel. The
specific tools are the openssl_tpm2_engine, openconnect and the Intel
tpm2-tss-engine. To do that, we have to be able to read and write the same
binary key format the tools use. The current ASN.1 decoder does fine for
reading, but we need pieces of an ASN.1 encoder to write the key blob in
binary compatible form.
For backwards compatibility, the trusted key reader code will still accept
the two TPM2B quantities that it uses today, but the writer will only
output the ASN.1 form.
The current implementation only encodes the ASN.1 bits we actually need.

When tpm_read_log_efi is called multiple times, which happens when
one loads and unloads a TPM2 driver multiple times, then the global
variable efi_tpm_final_log_size will at some point become a negative
number due to the subtraction of final_events_preboot_size occurring
each time. Use a local variable to avoid this integer underflow.

a799c2bd29d1 ("x86/setup: Consolidate early memory reservations")
moved reservation of the memory inaccessible by Sandy Bride integrated
graphics very early, and, as a result, on systems with such devices
the first 1M was reserved by trim_snb_memory() which prevented the
allocation of the real mode trampoline and made the boot hang very
early.
Since the purpose of trim_snb_memory() is to prevent problematic pages
ever reaching the graphics device, it is safe to reserve these pages
after memblock allocations are possible.
Move trim_snb_memory() later in boot so that it will be called after
reserve_real_mode() and make comments describing trim_snb_memory()
operation more elaborate.
